with an individual terminal strip for control wiring. Terminal strip metallic materials shall
be tinned copper. Power distribution blocks shall be tinned copper which is rated for termination
of copper conductors.
I. Combination starter control wiring shall be 14AWG. Power wiring shall have black insulation
and control wiring shall have purple insulation for ungrounded conductors and white insulation
for grounded conductors. Combination starter wiring shall have copper conductors with
MTW insulation only.
J. Where control transformers are indicated and unless shown otherwise, each starter shall contain
a 480 to 120 volt fused control transformer with sufficient capacity for all the devices
shown in the schematic. The control transformer shall have two (2) primary fuses, one in
each primary lead and one secondary fuse in one of the secondary leads. The unfused secondary
lead shall be grounded.
K. Each combination starter shall have an engraved plastic nameplate fastened to the outside of
